<FONT color="green">062</FONT>     * &lt;li&gt;&lt;b&gt;Sections:&lt;/b&gt; Ini files are split into sections, each section<a name="line.62"></a>
<FONT color="green">063</FONT>     * starting with a section declaration. A section declaration starts with a '['<a name="line.63"></a>
<FONT color="green">064</FONT>     * and ends with a ']'. Sections occur on one line only.&lt;/li&gt;<a name="line.64"></a>
<FONT color="green">065</FONT>     * &lt;li&gt;&lt;b&gt;Parameters:&lt;/b&gt; Items in a section are known as parameters.<a name="line.65"></a>
<FONT color="green">066</FONT>     * Parameters have a typical {@code key = value} format.&lt;/li&gt;<a name="line.66"></a>
<FONT color="green">067</FONT>     * &lt;li&gt;&lt;b&gt;Comments:&lt;/b&gt; Lines starting with a ';' are assumed to be comments.<a name="line.67"></a>

<FONT color="green">073</FONT>     * There are various implementations of the ini file format by various vendors<a name="line.73"></a>
<FONT color="green">074</FONT>     * which has caused a number of differences to appear. As far as possible this<a name="line.74"></a>
<FONT color="green">075</FONT>     * configuration tries to be lenient and support most of the differences.<a name="line.75"></a>
<FONT color="green">076</FONT>     * &lt;/p&gt;<a name="line.76"></a>

<FONT color="green">078</FONT>     * &lt;p&gt;<a name="line.78"></a>
<FONT color="green">079</FONT>     * Some of the differences supported are as follows:<a name="line.79"></a>
<FONT color="green">080</FONT>     * &lt;ul&gt;<a name="line.80"></a>
<FONT color="green">081</FONT>     * &lt;li&gt;&lt;b&gt;Comments:&lt;/b&gt; The '#' character is also accepted as a comment<a name="line.81"></a>
<FONT color="green">082</FONT>     * signifier.&lt;/li&gt;<a name="line.82"></a>
<FONT color="green">083</FONT>     * &lt;li&gt;&lt;b&gt;Key value separtor:&lt;/b&gt; The ':' character is also accepted in place<a name="line.83"></a>
<FONT color="green">084</FONT>     * of '=' to separate keys and values in parameters, for example<a name="line.84"></a>
<FONT color="green">085</FONT>     * {@code var1 : foo}.&lt;/li&gt;<a name="line.85"></a>
<FONT color="green">086</FONT>     * &lt;li&gt;&lt;b&gt;Duplicate sections:&lt;/b&gt; Typically duplicate sections are not allowed ,<a name="line.86"></a>
<FONT color="green">087</FONT>     * this configuration does however support it. In the event of a duplicate<a name="line.87"></a>
<FONT color="green">088</FONT>     * section, the two section's values are merged.&lt;/li&gt;<a name="line.88"></a>
<FONT color="green">089</FONT>     * &lt;li&gt;&lt;b&gt;Duplicate parameters:&lt;/b&gt; Typically duplicate parameters are only<a name="line.89"></a>
<FONT color="green">090</FONT>     * allowed if they are in two different sections, thus they are local to<a name="line.90"></a>
<FONT color="green">091</FONT>     * sections; this configuration simply merges duplicates; if a section has a<a name="line.91"></a>
<FONT color="green">092</FONT>     * duplicate parameter the values are then added to the key as a list. &lt;/li&gt;<a name="line.92"></a>
<FONT color="green">093</FONT>     * &lt;/ul&gt;<a name="line.93"></a>

<FONT color="green">095</FONT>     * &lt;p&gt;<a name="line.95"></a>
<FONT color="green">096</FONT>     * Global parameters are also allowed; any parameters declared before a section<a name="line.96"></a>
<FONT color="green">097</FONT>     * is declared are added to a global section. It is important to note that this<a name="line.97"></a>
<FONT color="green">098</FONT>     * global section does not have a name.<a name="line.98"></a>
<FONT color="green">099</FONT>     * &lt;/p&gt;<a name="line.99"></a>
<FONT color="green">100</FONT>     * &lt;p&gt;<a name="line.100"></a>
<FONT color="green">101</FONT>     * In all instances, a parameter's key is prepended with its section name and a<a name="line.101"></a>
<FONT color="green">102</FONT>     * '.' (period). Thus a parameter named "var1" in "section1" will have the key<a name="line.102"></a>
<FONT color="green">103</FONT>     * {@code section1.var1} in this configuration. Thus, a section's<a name="line.103"></a>
<FONT color="green">104</FONT>     * parameters can easily be retrieved using the {@code subset} method<a name="line.104"></a>
<FONT color="green">105</FONT>     * using the section name as the prefix.<a name="line.105"></a>
